| contents | El Niño-Southern Oscillation and precipitation history in Baja California: reconstruction using tree ring records Nora E. Martijena Ciencias de la Tierra climate El Niño Tree rings precipitation Baja California Tree ring records from northern Baja California were used for reconstructing annual series of precipitation and El Niño-Southern Oscillation. Reconstructions were compared to instrumental and historical records for verification. Five tree ring widthchronologies were developed using standard dendrochronological and statistical techniques: one of Pinus coulteri, two of Pinusquadrifolia and two of Pinus jeffreyi. One of the latter updated an existing chronology and doubled its period of calibration withinstrumental climatic data. The length of the chronologies was 101 to 551 years. All the chronologies had significant correlationswith precipitation records from Ensenada, Baja California and San Diego, California and with an ENSO-related index based oninstrumental records. Precipitation explained 8 to 57% of the variation in tree growth. Precipitation records were related to SOI(R2adj: 48 and 16% respectively), but tree ring chronologies captured weaker and more variable signals (R2adj : 3 to 24%). Agreementbetween historical documentary records and the tree ring reconstructed SOI with the highest predictive ability was 82%.Further research to extend the shorter reconstructed chronologies, which now show the strongest precipitation and ENSO signals,and further study of other sites and species from Baja California, is suggested. 2003 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56842307 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.42 |
